If you want to really, really save money,.... then avail yourself of prescriptions that are made available throughout the Commonwealth Nations... ie: Canada, UK, New Zealand, Bahamas, India etc.

I have been purchasing from certified, CIPA member Canadian pharmacies for over 10 years. Specifically for asthma inhalers.
Below, I will tell you the savings I incur. And I will address my personal opinion on safety.

The Canadian pharmacy I use right now is GlobalCareRx.com. I used to use NorthwestPharmacies.com or CheapoDrugs...but the latter two companies stopped carrying the cheaper generics.

Advair is the brand name of a long lasting inhaler made by GlaxoSmithKline. Cash purchase in the US is about $300. I order mine, a product made for GSK by Cipla in India. I get 3 of the 125/25 inhalers, with 120 inhalations for just $73. That is right... these 3 inhalers I get, which has the same amount as stateside inhalers cost $73 versus paying $900 cash in the US.
A LOT of folks use the Albuterol inhalers like Ventolin, Proventil, etc. When I order from GlobalCareRx, they come from the UK. I can get 6 inhalers for around $60. vs 1 inhaler stateside for $60 cash. Ten dollars each versus Sixty.. Dohhh!

Go there and type in your pharmaceutical drug in the search engine and see the prices, and what they offer. You can get name brand.. or generics that are sold for distribution throughout the Commonwealth Nations.

Safety. Let me ask you a question. Suppose you used an inhaler from time to time, and were on vacation in England. You lose yours, so you go to the doctor, and he sends you out to fill your need. Question: Would you fear the safety of the inhaler? What if you were in India, New Zealand, or Australia. The answer is Of Course Not. Now then, there are scan distributors, websites, etc. What they do is take your card, run up a charge and send you nothing! The ones I listed are legitimate. You can have them call your doctor to obtain a Rx, or even transfer an existing one. They WILL NOT DISPENSE OR TAKE YOUR ORDER WITHOUT A VALID PRESCRIPTION.

I just ordered 3 advair type made for GSK in India, 6 albuterol, fast acting inhalers, free shipping.. for $125 total!. A cash patient, some struggling mom trying to work two jobs just to help her child breathe, would have paid $1200 for that, without insurance.. cash price! Now, you would think Dr. Phil, Dr. Oz et al would do our fellow citizens a favor and let them know about a list of REAL CANADIAN PHARMACIES...but why don't they? Obviously, the networks get wayyyyyyyyy too much pharma ad revenue.

So there you go. By the way, this is my disclaimer to you. I am not a physician. I am not a salesman. I receive zero benefit if you go there. (However.. if YOU create an account, and YOU are happy, and YOU introduce a family member or friend, you will save some additional $$$. Notice I did not give you my CheapODrugs, or GlobalCareRx member #. I do NOT want any benefit) Talk to your doctor. But by all means, go and visit the sites I gave you. Call, ask questions, they are legitimate pharmacies that are part of the Canadian network (CIPA). They have products sent to your from Commonwealth nations. I have had items that originated from, New Zealand, Austrailia, UK, India, and Bahamas. All just fine.
